The opening scene of Seven establishes a sense of confusion, disorientation, and fear through various techniques. Shots are shown in low light making them indistinguishable, mirroring the detective's future state of mind. Interspersed are extreme close-ups of a razor blade and flashes of injured people, foreshadowing the violence to come. Deteriorating background music adds to the fear and could reflect the deterioration of the killer and detective's mental states. The character appears to be making a scrapbook that becomes an important element, suggesting an obsession. Low lighting casts long, ominous shadows that convey negativity and horror.
